The Malaysian Grand Prix: an
abrasive surface with high heat and humidity makes this race a true test for
drivers, cars and tyres. Nearly every afternoon there is an intense
downpour, making it likely to see the Cinturato tyres in competitive action
for the first time this year.
Paul Hembery, Pirelli motorsport director: “The Australian Grand Prix
two weeks ago confirmed what we saw in testing: lap times that are two
seconds or more faster this year compared to last year, in every session.
This exponentially increases the workload on the tyres: something that will
be particularly in evidence at Sepang, which has some of the most abrasive
asphalt we race on all year and a number of fast corners that take a lot of
energy out of the tyres, as well as high ambient temperatures. For all these
reasons, we have chosen the two hardest tyres in our range this weekend: P
Zero Orange hard and P Zero White medium, as has always been the case in
Malaysia since we returned to Formula One in 2011. We should see a return to
at least two stops per car in Malaysia – perhaps more if the weather gets in
the way – after an early safety car meant that unusually most drivers
stopped only once in Australia. Wear and degradation is traditionally very
high in Sepang, so managing the tyres and the strategy carefully will be key
to success.”
The biggest challenges for the tyres:
Malaysia has got everything it takes to make life difficult for tyres: fast
corners with big lateral loads, rough asphalt, high ambient temperatures and
a bumpy surface (as the track was originally built on a swamp). As a result,
both mechanical and thermal degradation are important factors. The cars tend
to run high downforce in Malaysia, adding vertical forces to the varied
demands faced by the tyres.
Because it rains almost on a daily basis in Sepang, the rubber laid down on
the circuit tends to get washed away between each session. This makes the
pattern of track evolution quite hard to predict, and also increases the
risk of race stoppages and safety cars (the Malaysian Grand Prix has been
halted early on more than one occasion). Drainage is a problem, leading to
pools of standing water.
If it does rain during the race, judging the crossover point could make the
difference between winning and losing. This is the point at which it becomes
faster to switch from one type of tyre to another. With very little wet
running so far this year, teams will prioritise gathering information on
crossover points if it rains during free practice: data that could be
crucial for the race.
The most stressed tyre in Malaysia is the front-left, so this is the one
that the drivers will have to watch: especially at the beginning of the race
when the cars are fuel-heavy and it is easy to lock up and take life out of
the tyres.
Last year’s strategy and how the race was won: The top two finishers in
Malaysia last year (Lewis Hamilton and Nico Rosberg) used exactly the same
three-stop strategy: three stints on the medium tyre followed by a short
stint on the hard tyre at the end. They fought closely for the lead, with
tyre strategy proving crucial to their battle, while the highest-placed
two-stopper was Nico Hulkenberg in fifth. The race lasts 56 laps.
Expected performance gap between the two compounds: 1.0-1.2 seconds per lap.
Expected weather conditions for the race: Temperatures between 24 and 34
degrees centigrade and 80% humidity, with a high risk of heavy rainfall
during the late afternoon.
The Pirelli team choose their race numbers: #27, Mario Isola (Pirelli
racing manager)
“I would choose 27, as it was Gilles Villeneuve’s number when I was first
getting into Formula One, at the end of 1980 when I was 11 years old. And
from then on, I was constantly badgering my father about racing, until he
gave in and bought me a kart, which I raced with number 27. Since then 27
has always been my lucky number.” |
